The most important diagnostic characteristic is the ability of the E. coli strain to produce the Shiga toxin Stx2. Therefore, the stools should be assayed with a sensitive and specific test that detects the toxin gene stx2 or the isolation of the pathogen with the detection of Stx2 production or theRead more

Therefore, the stools should be assayed with a sensitive and specific test that detects the toxin gene stx2 or the isolation of the pathogen with the detection of Stx2 production or the gene encoding it. The detection of Stx using ELISA directly from stool has a low specificity.

Enteric fever, also known as typhoid fever, is caused by the bacteria Salmonella Typhi (S Typhi) and Salmonella Paratyphi A and B. The pathogenesis of enteric fever depends on a number of factors including the infecting species and infectious dose. Ingested organisms survive exposure to gastric acid before gaining access to the small bowel, where they penetrate the epithelium, enter the lymphoid tissue, and disseminate via the lymphatic or hematogenous route.
